HEEL-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,419, dated December 6, 1887.

Application filed December 15, 1886. Serial No. 221,619. (No model.)

To all whom it may concern..-

Be it known that I, WILLIAM MANLEY, of Rochester, county of Monroe, and State of New York, have invented an Improvement in Heel- Trimming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement upon United States Patent No. 322,945, granted to me July 28, 1885, and has for its object to improve the construction of the same in many particulars.

One feature of my present invention consists in a counterguard with which is combined means for adjusting it with greater ease and accuracy with relation to the heel'trimming cutter. I have also provided a hammering-up tool or wheel for hammering up the rand and heel, the said tool or wheel being secured to the shaft carrying the rand-cutter, and being capable of movement longitudinally upon said shaft toward the rand-cutter, so that either the rand-cutteror the hammeringup tool or wheel maybe employed to act upon the heel at the will of the operator, the same heel-rest being employed to support the heel in either instance, which heel-rest is preferably adjustable.

Figure 1 shows in front elevation a heeltrimming machine embodying this invention; Fig. 2, a top view of the machine shown'in Fig. 1; Fig. 3, a sectional detail of a portion of the machine, taken on the dotted line as m, Fig. 1; Fig. 4, aleft-hand end view of the head of the machine shown in Fig. 1, and Fig. 5 a detail to be referred to.

The post or standard A, supporting the frame B, the revolvingspindles NO, theheeltrimming cutter 70, carried by the shaft N, the top-lift support 9, adjustably connected with the said frame, the heel-rest Z, also connected with the frame, and rand-cutter it, carried by the spindle O, and the hammering-up tool or wheel K, also carried by the said spindle O, are all substantially as in the patent'referred to, to which reference may be had, like'letters of reference indicating like parts.

In the present instance of my invention the counter-guard C, as shown, consists of a strip loop. The ends 6 7 of the said strip of metal are extended into bearings in a block, C, secured to or forming an integral part of the slide 0". The slide C enters the bearing C made preferably as a splithub pressed together by the screw C*. The said slide hasa projecting spline, which cooperates with the split hub to prevent rotation of the slide, yet permitting the said slide, with its attached counter-guard C, to be moved toward or from the cutter longitudinally.

The portion of the counter-guard Csnrrounding the spindle 'N adjacent to the heel-trimming cutter is is of such shape in the direction of its width'as to conform to the curves of the counter which is to be borne against it.

The counter-guard C is adapted to be moved toward and from the surface of the spindle N by an adjusting-nut, 0, applied to the screwthreaded end of the portion 6 of the counter guard which protrudes through the block 0. A spring, 8, seated within the block C,.surrounds the portions 6 7 of the counter-guard, one end of each spring bearing against the block C, while the other end bears against a shoulder formed upon the portions 6 7. To the upper side of the portion 6 of the counterguard a stud or hook, 0, is secured, and to the block 0 a beltcrank lever, 0 is pivoted, one end of the bell-crank lever being connected with the said hook or stud c by a link, 0 the opposite end of the said bell-crank lever being connected by a treadle-rod, c, with a treadle, c, pivoted at c to the base of the machine.

By depressing the treadle 0" the counten guard is moved for a short distance-as, for instance, one-sixteenth of an ineh-to vary the relative distance from each other of the concaved surface of the counter-guard and the cutting-edges of the heel-trimming cutter is, a suitable pin, 9, being screwed into the block 0, against which the end of the portion 7 of the counter'guard strikes when the treadle is thus depressed. The object of this adjustment of the counterguard toward and from the cutting-edges of the cutter is to permit the heel to betrimmed to produce a fine or a heavy heel-seat at the will of the operator.

of metal bent into U shape, or bent to form a The top-lift rest 9 has a shank, g, mounted between two clamps or jaws, g 9 adjustable with relation to each other by the adj ustingscrew g, said clamps or jaws being carried by a frame, mounted upon the spindle N. By loosening the adjusting-screw g the said top- -lift rest or support may be adjusted toward and from the cutting-edges of the heel-trimming cutter. The frame has a projection or arm, 9 provided with two laterally-extended arms, one of which, as passes through the bearing-block B, mounted upon the frame B, and the other, as 9, passes through the block g A spiral spring is seated within the block B, one end of which bears'against the interior of the block, while the other end bears against a shoulder formed upon the arm 9 said spring normally pressing the arm, and consequently the frame 9 toward the heel-trimmer, and an adjusting-screw, 9 is turned upon the screw-threaded end of the arm and by bearing against the block 9 limits the movement of the frame 9 toward the cutter. The heel-rest Z is bolted to the under side of the block 9 and may, if desired, be made adjustable by forming the hole as a slot, through which the bolt passes.

The spindle N is rotated by a belt, B, which passes around a pulley, B, fast to it, and also around the belt-pulley B secured to the driveshaft B at the base of the machine, which shaft B is rotated in any suitable manner-as by the drive-wheel B A balancewheel, B is also fast to the spindle N.

A belt, B", passes around a pulley, 13 fast to the spindle N, and also around a pulley, B, fast to the spindle O. The rand-cutter k is secured to the end of the spindle O, and a heel-rest, It", is bolted to that portion of the frame B in which the spindle O has its bearlngs.

The hammering-up wheel K has a screwthreaded shank portion, 12, splined to the spindle O, the said shank portion entering an adjustable block, K, which is suitably recessed to receive it. A nut, 13, turned upon the screw-threaded shank portion 12 of the hammering-up wheel, fits the recess in theblock K. The block K has a suitable shank, K, which enters a passage cut in that portion of the frame B in which the spindle O rotates. The shank K receives into it asuitable headed stud, K", which is passed through a slot cut in one side of the said bearing portion of the frame, movement ofthe stud in the direction of the length of the shank causing the hammering-up wheel to be moved toward or from the rand-cutter K.

\Vhen it is desiredto employ the hammering-up wheel, it is moved by the headed stud K against the face of the rand-cutter K, said hammering up wheel being considerably larger than the said rand-cutter, so that the heel bearing upon the heelrest 7c will be acted upon by the said hammering-wheel to hammer up the rand and heel-seat.

The heel-rest may be adj ustably connected with the frame in the manner shown in Fig.

5, and in such instance the said frame is provided with a lug, 15, through which passes a screw-threaded bolt, 16, provided with checknuts 17, 18, and 19, the said heel-rest being interposed between the check-nuts 18 19. The heel-restl may also be adjustably connected with the frame or block in a like manner, if desired.
